Does this main isolator switch require a separate enclosure ?

[Paul N]

Hi Everyone,
Thank you in advance for your assistance, I"m assuming that having an unenclosed main switch is against the rules ?
Should it be sited within the same Consumer Unit or a separate enclosure ? The Consumer Unit, meter and main switch are housed within a wooden formica cupboard (2nd photograph).
Many thanks for your advice re any necessary changes that need to be commissioned.
Regards, Paul

The consumer unit has been "adapted". The left rcd switch would have been an en60947-3 switch which isolated the whole board. This has been replaced by an rcd so who knows whether this rcd still isolates the lot.

Do ARC electrical still exist?

im struggling to think of a regulation that has been broken here TBH. I suppose it does have a means of isolation, but......

..... don’t like it.

IP rating for one I would hazard a complete guess

Assuming the internals of the CU are correctly configured it should be ok. It would be interesting to see how they are powering both RCDs. No different from an MEM Exel fuse board for example with an external isolator. It should be marked 'main switch' though.

That is the DNO isolator switch look at label fitted by Morrison data meter installer

Looks good as gold to me , probably one of the better consumer units I have seen this year

I quite like artistic work on labelling all PD's

Sure is. Looks like someone's arranged it because of lack of isolation at the CU.

It wants sorting out.

Could always put a lock on the cupboard door if concerned about it !
I'm failing to see any real issue with it

Whoever did the initial install of the M/S needs shafting with a prickly stick, preferably without an anesthetic.

So you're saying... if a DNO isolator has been fitted, the CU main switch can be removed by doctoring?

At least the circuit cables are neatly dressed and clipped. Oh wait.

What about inquisitive children getting their grubby fingers and the like in the open terminals? not a good idea is it think about it. a bad move in my book , but mind you I am old School and value the safety regulations. fallen foul of the a few time myself, not good seeing a nipper that has stuffed his/her carbon pencil into anun covered terminal with 230 Volts hanging on the ed of the pencil, could you live with it
' I couldn't your choice Mate

Multiple bonuses there, you get 2 extra ways and a main switch you can sell on ebay!

What open terminals?

Bet it's one hell of a mess inside that unit, too.

 

[Timbo]

At a guess the switch at the side of the D/B?

That's an MEM 100a isolator. Probably installed by the electricity supplier.
